Hi! I have a question about enclosures

I just bought 2 DIAMOND AUDIO M6 12” subs and the manual says it needs between .6-1.75 cu. Ft of airpspace EACH..

That’s a pretty big range! I have two boxes, one of 1.7 total, so .875 each and also, 2.5 total so 1.25 each.

My question is what is the difference in the volumes, whats different if thers the least amount vs. the most airspace…

I tried the subs on the .875 each and they sounded “middy” I guess you can call it.

I am running a JL 500/1 amp to these and they are rated at 800 RMS for both

Thank you very much

First of all the subs will need about 1 month of playing time to loosen up and act the way they were designed to act. Expect this to help the efficiency and bass extension. Second, on to enclosures -

Smaller will have a bump in the midbass response and a sharper low frequency roll off. And greater power handling. Problems are that with the lower box resonance you will need more power to hit the low notes hard. And the sub will not be as efficient as in a larger box.

Larger will have a smoother response. Greater low frequency extension and less or no bump in the midbass region. Also greater efficiency. But with the greater efficiency your power handing will go down. It will take less power to push the sub to it's mechanical limit. But this is actually a good thing. Because why buy a 1000 watt amp when a 500 watt amp will push the sub as hard as it can be pushed without excessive stress. Some don't like the extra bass thump in the low frequencies. For those poor souls you can turn down the lowest frequency on your eq, or raise the infrasonic filter frequency.

 

ok got it, thanks a lot! i appreciate it =]
i had taht sort of idea but i didnt know how the power was affected..

thanks!
